Still brainstorming the idea of using Stickvise for PCB milling. After a brief chat on Twitter with Danielle Applestone (owner of Other Machine Co. makers of the Othermill) I was inspired to delve further into this possible application. The main issue is full slotting, particularly parallel to the edges of the jaws where the PCB is most likely to slip. This morning I did some testing to see how Stickvise would handle this.
Below are the results, not a bad start - didn't have movement in any of the five test boards I cut out.
Sorry for the absolute bush league mistake of putting my finger over the lens, that's embarrassing. You can see more about the jaw design I'm using in this older project log.
The info on the cut is as follows -
Machine: Tormach 770
Spindle Speed: 10,000 RPM
Feed Rate: 10 in/min
Tool: 1/8" diameter, 2 flute carbide endmill, uncoated, general purpose (I think I got it from McMaster)
